Symptoms
About 3 weeks ago, Helldivers 2 started launching on Intel GPU only, and not NVIDIA GPU, and the game can only see the Intel GPU, even though I have an NVIDIA Optimus system. The game had been properly launching on NVIDIA GPU for several months, but suddenly stopped. I tested launching the game with Proton Hotfix & Experimental, and with various CLI options: PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only MESA_VK_DEVICE_SELECT=0 %command% but nothing works.
Reproduction
Launch Helldivers 2 on nvidia optimus system with Proton Hotfix & Experimental
